I think this is the bigger issue. I'd agree that buying healthy options at the grocery store does not have to be more expensive than junk food (or even cheaper), but that's assuming you can plan ahead well enough to not throw away the fresh food once it spoils. Granted, that's a matter of habit, but a hard habit to overcome if you're not used to it. I rarely shop in the middle of the grocery store, except for staples, but I still manage to throw a bit away a week later.
